Observed in NetScaler 11.0 Builds 65.x, 66.x, 67.x, 68.x
Actions in Outlook, such as sending/receiving mail result in changes to the Outlook search index database. This data is stored in the Windows search index database: Windows.edb.
This is a machine-based file, which means it holds search index data for all users logging onto the machine. If a user launches an Outlook session (or opens Outlook in a desktop session) on a VDA machine that they haven’t access previously or haven’t accessed for a while, the Outlook search index has to be rebuilt in Windows.edb. Outlook searches have to wait until re-indexing finishes. The location of the Windows search index database is typically: C:ProgramDataMicrosoftSearchDataApplicationsWindowsWindows.edb
We can see this design in the image below:
Behavior using VHDX-based Outlook cache and Outlook search index on a user basis
The Profile Management 7.18 release introduced a feature to address these Outlook-related performance challenges.
To explain we’ll use the same user as above, but logging on to a 7.18 version VDA for the first time.
During the Profile Management logon, the user’s Outlook-related search index is split out of the Windows search index database (Windows.edb) and written to a VHDX file created at:
The remote VHDX file is then mounted locally in the user’s local profile at:
From this point, the user has their own profile-based version of the Outlook search index database. Within the Search.vhdx mount-point folder, the Outlook search index database is named < userSID>.edb
The Outlook .OST file is converted into a VHDX file and stored at:
The remote VHDX file is then mounted locally in the user’s local profile at (default):
During the Outlook session, changes to the Outlook search index and Outlook .OST are made directly to their respective VHDX files over SMB.
The feature also requires additional registry settings to be created. Read the Registry Changes section for further information.
When the user logs off the session, both VHDX files are unmounted from the local profile. Because the VHDX files had been mounted over SMB, no synchronization is required at Profile Management logoff. The additional registry settings are synchronized to the user’s profile store (or before if the Active Writeback Registry feature has been enabled).
Feature Enhancements introduced in Citrix Virtual Apps and Desktops 1808
The Profile Management 1808 release Outlook search index feature supports groups explicitly excluded through the Profile Management Excluded Groups policy as well and groups implicitly excluded through the Profile Management Processed Groups policy (see Feature Limitations for further information).
This release also introduced support for Windows 10 1803.
It’s inevitable. You send someone an email in Microsoft Outlook. And then you realize for one reason or another that the message has a mistake or that it shouldn’t have been sent at all. You can fix your error after the fact by recalling a message. Using the recall feature under the right conditions, your previous email is deleted without the recipient ever seeing it. You can also send a replacement message with the correct information.
SEE: How to add a drop-down list to an Excel cell (TechRepublic)
There are some requirements if the recall feature is to work properly. For your recalled message to be deleted, both you and the recipient must have a Microsoft 365 Business account or Microsoft Exchange email account in the same organization, meaning the same Exchange system on the backend. The email must have been delivered to the recipient’s mail server but it must not have been read yet.
However, even if you and the recipient use different email clients or backend systems, or you fail to recall the message before it’s been read, the recall feature can still serve a purpose. Though the initial email won’t be deleted, the recipient receives a follow-up message indicating that you want to recall the previous email. That tells them that your initial email is incorrect or invalid for some reason. You should then follow up your initial email and recall message with another email that contains the right information or corrects the initial one.

To try this, open Outlook. Start a new email and address it to the recipient. Send the email (Figure A).
Now, let’s say you notice an error in your email and want to recall it. Open the email from your Sent Items folder. Select the Actions icon and click the option to Recall This Message (Figure B).
The Recall This Message window offers two options. Choosing to “Delete unread copies of this message” tries to remove the message with no follow up. Choosing to “Delete unread copies and replace with a new message” gives you an opportunity to immediately send a follow-up message with the correct information. To learn if the recall succeeds, keep the box checked for “Tell me if recall succeeds or fails for each recipient.” Click OK (Figure C).
If you chose the option to replace with a new message, a new email appears with the text from the original message so you can fix the problem and send the corrected version (Figure D).
If you and the recipient use the same Microsoft 365 Business or Exchange backend environment, then the email should be deleted from the recipient’s inbox automatically. If so, you’ll receive an email indicating that the recall was successful for that particular user.
If you and the recipient use different email clients or backend mail services, the initial email remains in that person’s inbox. A follow-up email then arrives that tells the recipient that you would like to recall the message. You then have to rely on your recipient to ignore or delete the original message in favor of the corrected one (Figure E).

It is recommended that you follow point 4 above before moving on to create a new profile. Rename the folder that you can’t expand in Outlook. Right-click on the folder and select the Rename option to do so. Take a backup, if you must. If you have taken a backup on the server or in the cloud, delete the profile the below mentioned:
Of course, the Username above and the drive letter should be your corresponding user name and Windows installation drive. Reboot your computer.
Open Outlook and under the Files menu, click on Account Settings > Manage Profiles.
Click on Show Profiles.
Click on Add to begin creating a new profile.
You can now add email accounts to this newly created profile and check if you still get the Cannot expand folder error.
The Outlook email account data is stored in a .PST file if you are using IMAP or POP account. The same is stored in a .OST file if you are using Office 365 or Exchange account. Depending on the email account throwing the Cannot expand folder error in Outlook app, choose one method.
Repair OST File
Open Control Panel and go to User Account > Mail > Show Profiles. Select the profile you are having trouble with and click on Properties below. Now select Data Files in the pop-up that follows.
Select the email account data file and click on Open File Location.
A new window will open with a file name with .OST extension. Delete the file and reboot your computer. Launch Outlook and it will recreate the file automatically.
Repair PST File
The same steps won’t work for .PST file. Press Windows key+R to open the Run prompt. Enter the below file path in case of Office 2016, Office 2019, and Office 365.
C:Program Files (x86)Microsoft OfficerootOffice16
For Outlook 2013:
C:Program Files (x86)Microsoft OfficeOffice15
Double-click the SCANPST.EXE file, which will launch the Microsoft Outlook Inbox Repair experience. I wish there was a direct way of launching it.
Click on Browse on the pop-up that follows.
A new File Explorer window will open. You need to locate the .PST file here and when you find it, click on the Start button.
Select ‘Make a backup of scanned file before repairing’ option to create a backup in case something goes wrong.
Now click on Repair to begin the process.

NET Framework Incompatible
For best performance, it is recommended that users download the most recent version of the .NET Framework before using the plugin.
Multiple Outlook Profiles or Emails

Outlook Plugin and Trend Micro
Trend Micro customers may experience crashing, difficulty accessing the ShareFile Plugin, or a “fading” Outlook ribbon that results in an app crash. This may be due to high CPU usage caused by the Trend Micro Security program. Click here for information and troubleshooting steps from Trend Micro.
3rd Party Services and Add-Ins
The ShareFile Outlook Plugin is not supported with any 3rd party service or add-in and cannot be guaranteed to function properly when used in conjunction with other add-ins. This includes (but is not limited to) meta-data scrubbers, SmartVault, iTunes, Grammarly, NETDocuments, and other add-ins. If you are using an antivirus program or add-in such as Norton, Kaspersky or McAfee, please take steps to add ShareFile as an exception to your apps. Metadata Scrubbers may interfere with the ShareFile Plugin for Microsoft Outlook. It is recommended that any metadata scrubber add-ons be disabled in order for the ShareFile Plugin to function properly. Likewise, Exchange Alternatives (such as Kerio Connector) are not compatible with the ShareFile Plugin and may block the plugin from functioning correctly. ShareFile recommends disabling these add-ons.

If your company has deployed ShareFile Restricted Zones and your default zone is a Restricted Zone, then you will be prompted to authenticate with your company credentials into that zone during the configuration of the plugin. If your default zone is not a ShareFile Restricted Zone but you attempt to share a file from a Restricted Zone using the Outlook Plugin, you will also be prompted to authenticate into that zone with your company credentials.
There are two versions of the MSI available:
In order to install the ShareFile plugin for all users on the PC, the appropriate version of the Installation file must be used.
If upgrading from a per-user MSI to an all-user MSI, you must first uninstall the per-user MSI. Click here for instructions on how to perform a per-machine upgrade of the ShareFile Plugin.
The all-users MSI installer does not support the Auto-Update option.
Administrators can automatically default and lock in preferences for the plugin in the Admin section of their ShareFile account, under Power Tools. Click here for information on how to configure defaults.

If you log in to Microsoft Outlook and your ShareFile Plugin appears to be missing, there is a chance your plugin was not installed properly.
To confirm this in Microsoft Outlook: click File, then select Options and navigate to the Add-Ins list. If the ShareFile Plugin is listed as “Inactive”, you may need to enable the plugin manually.
The ShareFile Plugin for Microsoft Outlook must be configured to work with your proxy setup. To do so, close Microsoft Outlook and run ShareFileProxyConfig.exe from C:UsersUSERNAMEAppDataLocalShareFileOutlookPlugin.
